摘    要:作者在研究了不同类型苹果砧木叶结构与矮化性能相关的基础上。进一步对茎结构进行了解剖学探讨。试验结果查明: 1.苹果砧木的矮化与否和韧皮部的厚度(不包括皮层厚度)有关,即:矮化砧韧皮部最厚,半矮化砧次之,乔化砧最簿。 2.不同类型乔矮砧,木质部的厚度分析与矮化关系,无规律可循。 3.对韧皮部与木质部的比值进行了分析,其不同类型砧木茎结构的韧皮部与木质部的比值为1∶2.4——1∶6.5,看来比值变化趋势愈小,愈趋向于矮化或半矮化,反之,则趋向于乔化。由上述几项测定比较,我们认为以砧木茎的韧皮部厚度作为预选苹果矮砧的方法之一,是具有重要的实用价值。

关 键 词:苹果矮化砧木  预选指标  茎结构  解剖学

Abstract:After we studied the structure of the leaf blade of stocks of apples in relation to it's dwarfing, further we have studied the anatomy of the stem of the stocks. The experimental materials used in this study of the different stocks were M-system 1,2,3,4,5,6,7,8,9,13,15,26; MM-system 104, 106, 111 and arbor stocks-Malus baccata, M. asistica, M. honaensis and so on. The permanent sections for microscopic examination of the stem of stocks were treated by the sliding section method. The result showed: 1. The more thick thinkness of the phloem of the stem stockthe more dwarfing was; 2. There was not found of theapples law for the phellem cortex, phloem fiber, xylem and pith in relation to the dwarfing. This study can be applied in selecting the dmarfing stocks.
Keywords:The dwarfing stock of apples  Anatomy structure
